About (claimed) apostolic succession

“[The apostles] were personally chosen, called and commissioned by Jesus Christ, and authorized to teach in his name. . . . There can, therefore, be no apostolic succession, other than a loyalty to the apostolic doctrine of the New Testament. The apostles had no successors. In the nature of the case no-one could succeed them. They were unique.”
John R. Stott, Only one way: The message of Galatians, page 13.
